  2. Power electronics - Wikipedia

    en.wikipedia.org/wiki/Power_electronics

    A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves.

  3. Power semiconductor device - Wikipedia

    en.wikipedia.org/wiki/Power_semiconductor_device

    The first electronic device used in power circuits was the electrolytic rectifier - an early version was described by a French experimenter, A. Nodon, in 1904. These were briefly popular with early radio experimenters as they could be improvised from aluminum sheets, and household chemicals.

  4. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    From basic circuit theory, the power delivered to a device is optimized (MPP) where the derivative (graphically, the slope) dI/dV of the I-V curve is equal and opposite the I/V ratio (where dP/dV=0) [13] and corresponds to the "knee" of the curve. A load with resistance R=V/I equal to the reciprocal of this value draws the maximum power from ...

  5. Power MOSFET - Wikipedia

    en.wikipedia.org/wiki/Power_MOSFET

    NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%). [24]

  6. Flexible AC transmission system - Wikipedia

    en.wikipedia.org/wiki/Flexible_AC_transmission...

    While other traditional equipment can accomplish all of this, FACTs devices utilize Power Electronics that are fast enough to switch sub-cycle opposed to seconds or minutes. Most FACTs devices are also dynamic and can support voltage across a range rather than just on and off, and are multi-quadrant, i.e. they can both supply and consume ...

  7. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    The technology of wireless power transmission can eliminate the use of the wires and batteries, thereby increasing the mobility, convenience, and safety of an electronic device for all users. [2] Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.

  8. Solid-state transformer - Wikipedia

    en.wikipedia.org/wiki/Solid-state_transformer

    Variations can input or output DC power to reduce the number of conversions, for greater end-to-end efficiency. A Modular Solid-state transformer consists of several high-frequency transformers [1] and is similar to a Multi-level converter. As a complex electronic circuit, it must be designed to withstand lightning and other surges.

  9. Insulated-gate bipolar transistor - Wikipedia

    en.wikipedia.org/wiki/Insulated-gate_bipolar...

    The IGBT accounts for 27% of the power transistor market, second only to the power MOSFET (53%), and ahead of the RF amplifier (11%) and bipolar junction transistor (9%). [35] The IGBT is widely used in consumer electronics, industrial technology, the energy sector, aerospace electronic devices, and transportation.
